A farmer who was arrested last month expressed his displeasure Thursday afternoon in Newport by driving a heavy tractor over seven police vehicles owned by the Orleans County Sheriff’s Department, authorities said.

State police estimated the damage at about $250,000. No one was hurt.

Roger Pion, 34, was jailed for lack of $15,000 bail at the Northern State Correctional Facility in Newport to await arraignment Friday morning on 11 charges.
